Identification of Intermediate of the Metabolism of Methylthioadenosine by Cell-free Extracts of Actinoplanes ferrugineus


Abstract
To identify intermediate(s) during the conversion of methylthioadenosine to methionine by cell-free extracts of Actinoplanes ferrugineus, a compound was isolated from the anaerobic incubation mixture of cell-free extracts and CH_3-[^14C]-methylthioadenosine, followed by 0.01 N¡ªHCI hydrolysis. The compound was characterized through alkaline phosphatase treatment, NaBH_4 reduction, and NaBH_4 reduction¡ªperiodate oxidation reaction. The intermediate seemed to be 1-phospho-5-methylthio-5-deoxyribulose.
